Mhando dzemabheyaringi asina chinhu

 

Mukana uripo pakati pemugodhi nekuberekaInobata pamusoro, iyo inonzi bearing isina chinhu. Inoshandiswa zvakanyanya nekuti inosangana pamusoro inogona kutsungirira masimba makuru ekunze, haibatike nekudengenyeka, uye ine chimiro chakareruka. Semuenzaniso, majoini anofambiswa eExcavator's Monster Hand.

 

Mabheyaringi anotsvedzainogona kukamurwa kuita mhando nhatu zvichienderana negwara resimba, dzinoti:

 

1. Radial inotsvedza bearing

Kutungamira kwesimba remabheyaringi epachena eradial kwakatarisana nepakati peaxis, iyo inogona kukamurwa kuita mhando nhatu zvichienderana nechimiro:

 

1) Kubata kweIntegral: Kubata kweIntegral kutsvedza ibheya rinotsvedza rakajairika, iro rakabatana nefuremu nemabhoti. Kumanikidzwa kwemukati kwebhoya rechigaro chebheya, kapu yemafuta yakaiswa pamusoro peimba yebheya, gomba rekupinda kwemafuta riri paburi reshaft, uye nzvimbo yemukati yakazadzwa nebheya (kana shaft sleeve) yakagadzirwa nezvinhu zvinodzivirira kupwanyika kuti ivhure axial oil groove kuti iparadzire lubricating oil lubrication.

 

2) Matching bearing: Rudzi urwu rwebearing rwuri nyore kuisa nekuputsa, uye mutengo wakaderera, uye runoshandiswa zvakanyanya nehunyanzvi. Semuenzaniso, mabearing ari pamacrank emhando dzakasiyana dzeinjini dzemoto

 

3) Kutakura kwezvikamu zvina: kunozivikanwawo sekutakura kwezvikamu zvina, kunoshandiswa mumotokari hombe, dzakadai semainjini ekudzungudza, mainjini ekudzungudza uye mamwe mabheyaringi espindle.

 

Zvinhu zvakagadzirwa nemabheya asina chinhu zvinonyanya kushandiswa nesimbi yakakandwa. Nekuda kwekuoma kwayo, zviri nyore kukonzera kupera kwejenari, saka bhandi rinowanzo wedzerwa pakati peshaft nebheya. Zvinhu zvakagadzirwa nebhandi iri zvinonyanya kushandiswa nebronze, white alloy uye barbit alloy.

 

2. Kutsvedza kwesimba rekufambisa

 

Mutoro webheya resimbi rakapfava wakaenzana negwara re axial, iro risingangotsigire kutenderera kwemuchina chete, asiwo rinodzivirira kufamba ne axis. Rinogona kukamurwa kuita mhando ina:

 

1) Ring thrust bearing: yakakamurwa kuita:

 

(1) Kupinza kweringi imwe chete: Kupinza kweringi imwe chete, kunogona kumira kupinza kweringi imwe chete kumativi ese ari maviri.

 

(2) Kupinza kwesimbi ine ring dzakawanda: Rudzi urwu rweshaft runogona kutakura kupinza kwesimbi kumativi ese, kumhanya kwakanyanya uye mutoro unorema.

 

2) Kubata kwekirasi: kunozivikanwawo sepivot bearing, ibheya rinotsvedza rakaiswa pamucheto weshaft, saka rinonziwo base column thrust bearing.

 

3) Hydrodynamic lubrication thrust bearing: nzvimbo yekukweshana iri pakati peshaft nebearing inogadzirwa kuita nzvimbo yakakombama kana kuti block inotsveyama. Layer yehydrodynamic oil inoumbwa pamusoro penzvimbo imwe neimwe yakakombama kana block inotsveyama kuitira kuti shaft isabatane nebearing.

 

4) Hydrostatic bearing: Kana mutoro weyuniti yebearing wakakura zvakanyanya, hazvigoneke kugadzira firimu remafuta nekutanga kwestatic, saka hydrostatic bearing inofanira kushandiswa. Mvura (mafuta) inomanikidzwa nepombi uye inotumirwa pakati pezvikamu zviviri kuti ichengetedze mafuta panguva yekushanda. Nekuti mvura yacho inopihwa nenyika yekunze, inonziwo external pressure bearing. Kana pressure yemafuta epombi ikachinjwa kuita air pressure, inonzi hydrostatic air bearing.

 

3. Mabheyaringi akakosha anotsvedza

 

1) Bearing ine maburi: inozivikanwawo se bearing ine mafuta, inotsemuka nenzira yekutsemuka kwesimbi yeupfu. Inowanzo kukodzera mabearing ane mitoro yakareruka.

 

2)Mabheyaringi asina mafuta: ane simba rakanaka rekupfeka, akakodzera michina yekugadzika chikafu isina mutoro wakareruka uye isingasvibisi, senge mabheyaringi eNelong.
